A crossover with Bungo Stray Dogs, Katekyo Hitman Reborn!, Honkai: Star Rail, and other IPs. The second world is 2.5-dimensional.
Main pairing: the Dominator; main character is the bottom.
People who know Yusaka Noboru always ask him the same question.
“Does having the ability of [Immortality] mean there’s nothing left to fear?”
After witnessing thousands of years of history unfold, Yusaka Noboru has a preliminary answer.
No.
He fears the graves of everyone.
He came from a vast universe, and after receiving a blessing from each of the Aeons, he was taken in by other worlds.
In this world, he witnessed a world war and the surging tide of human thought. He crossed the seas and arrived on a backward island nation, where he witnessed a grand feast of ideas among a group of writers.
He also made a promise to one of them: if he ever won the Akutagawa Prize, he would come back and celebrate with him.
But in the end, he jumped into a river, only to be buried beneath his own hopes.
Later, seeking the meaning of his own existence and trying to fulfill that person's wish, Yusaka Noboru joined an organization called the Vongola. Watching the passionate young people around him fight Byakuran day after day, all while holding fast to their dream of saving the world, Yusaka Noboru glimpsed the world's destruction in the future. So he used his own undying nature to take some of Byakuran's power and his rings.
Then, using the power granted to him by the Aeon of Elation, he forced his way into other worlds...
This is a world that once appeared in a manga.
Among ability users, one of whom bears the same name as an old friend,
he meets him once again...
